She starts the video with redness on her skin, which is then completely covered by the foundation.

Khan often posts makeup tutorials for acne-prone skin to her Instagram.

From giving people more confidence to being poised to outsell Kylie Cosmetics, there's not much that Fenty Beauty can't do — including, it seems, covering very red skin. On Monday, British makeup blogger Kadeeja Khan uploaded a video of herself applying Fenty Beauty Pro Filt'r Foundation on her Instagram account, Emerald Beauty. She starts off the video appearing to have artificially reddened her skin, as she does in some other videos. Without using any correctors or concealer, she ends up with immaculate coverage just by blending Rihanna's famous foundation.

Khan, who has severe acne, often posts selfies sans makeup, tutorials for other makeup-wearers with acne, and updates on her journey taking Roaccutane. "I find it very odd how people are very quick to judge others without looking in the mirror," she captioned one video. "Acne is perfectly normal and lots of us have it. I'm soo over the moon happy that @kendalljenner actually responded to the Internet trolls that made fun out of her acne. 'Don't let that s--- stop you,' which is very true!"

This isn't the first acne-covering tutorial Khan has posted that features Fenty Beauty. As Allure previously wrote, she has a tutorial that involves a color corrector and beauty oil before she applies the Fenty foundation. Since her new video just shows the potential of Fenty Beauty's coverage, this tutorial is a much more complete guide to covering acne, if one so chooses. "I made the video so that I can show girls with imperfect skin that they can use makeup and feel beautiful," she previously told Allure.
